P89C138/238 uses this method. other serial programming method uses device control programming. code updated through standard UART configured serial port. this method processor handles communication call program updates then erases programs FLASH memory. minimum programming hardware added accomplish erase reprogram. Small sections code changed P89C51RX+ P89C132. boot handler customized user depending application requirements.
OTP-EPROM
Philips offers more OTPs than other microcontroller supplier, providing effective solutions prototyping, low- high-volume production runs, applications requiring unique codes. each step design cycle, Philips' broad range user-programmable devices provides outstanding flexibility choice. From software development stage through device emulation system debug stage, FLASH devices most effective solutions your design challenges. Because these devices electrically erasable, reuse them until your design perfected. Early production phase, microcontrollers ideal because they provide flexibility make software changes quickly easily. many applications, devices being used volume production runs because they allow respond quickly changes production requirements. And, have make software change during production, devices allow software changes into production lower cost-because there (Non-Recurring Engineering) charges, work-in-process charges, need scrap large amounts inventory, none long lead times required mask devices. Best all, microcontrollers mean respond your market quickly.
EEPROM
EEPROM memory means decide when want program-either circuit programmer. With Philips 8XC864, 8XC858, 8XC855, 83C852 8XC851 offering range 80C51 microcontrollers that have EEPROM data memory. EEPROM data memory that stores critical data even when power turned off.
Speed Performance
Philips extended line high performance 80C51 microcontrollers that speeds 33MHz and, additionally, offers 8XC750 which operates 40MHz. This means have move more expensive microcontroller architecture processing power required. These microcontrollers which operate speeds 33MHz require less supply currents than previous designs. your design requires power dissipation speed that important, select from devices that operate down frequency, feature static operation, operate down 2.7V 1.8V. Philips developed processing capability that yields high speed voltage operation. Philips first offer OTPs with 2.7V operation without sacrificing speed. Philips extended performance features standard devices (8XC51/52/54/58 series) operate down 2.7V. your design requires more performance than obtain from 80C51 product line, select from compatible, high-performance, 16-bit microcontroller family.

ANALOG FEATURES
Selection guide 80C51 microcontroller family
PROTECTION CAPABILITIES REDUCED EMI/RFI
Philips family microcontrollers that contains extremely levels result easier certification, lower board design costs, simpler shielding solutions, easier power ground layout, reduced cross-talk. addition, Philips offers protection circuits, such Watchdog timers, oscillator-failure detection, low-voltage detection, giving shorter design cycles, lower system costs, external component requirements.
With reduced EMI/RFI devices, your design simpler, your costs lower, your power, ground layout, shielding simplified. using reduced EMI/RFI products, you're already step closer approval. example family reduced EMI/RFI devices 8XC575, which many techniques used reduce EMI/RFI level that times lower than emissions from standard 80C51 microcontroller. everything we've learned from 8XC575 been incorporated into growing list reduced EMI/RFI products.
Protection Circuits High Reliability
Reliability always design concern. This concern amplified when circuit used life-critical applications such medical instrumentation, aboard aircraft vehicles where circuit lock-up could disastrous. And, industrial applications, failure component could shut down entire production line. Philips offers wide range protection circuits that addresses these concerns with sophisticated built-in, hardware-based protection circuits that enhance your system's fault tolerance improve reliability: Watchdog timer, voltage detection, oscillator failure detection.
ADDITIONAL FEATURES
make your designs easier, Philips several specialty microcontroller products, each offered range packages.
On-Screen Display (OSD)
Philips OSD, featured 8XC055, 83C145 83C845 83C366/566/766, allows text over video easily, with surprising degree color shading flexibility. Philips offers user-defined character set, including font types sizes, starting position, character matrix, foreground background colors shadowing, well character blinking ratio vertical jitter canceling. With Philips many characters screen time. Both number rows number characters user-defined. Philips microcontroller capability offers design flexibility need custom tailor your system. addition, Philips combines that flexibility with hard-ware that makes simple include many different designs.
Watchdog Timer
Philips Watchdog timer designed fail-safe. Watchdog timer actually resets microcontroller within programmable time microcontroller enters potentially fatal processor state. user program fails reload Watchdog timer within specified time, Watchdog circuitry automatically generates system reset. Protection circuits, such Philips Watchdog timer, greatly increase designer's confidence that microcontroller will reliably recover from uncontrolled situations. Because Philips Watchdog timers hardware configured, they cannot corrupted software-based problems events that often occur microcontroller applications. added flexibility, Watchdog timer offers adjustable time-out period, from 512ms 12MHz oscillator depending demands your applications. (See also Counters/Timers section more information special features Philips Watchdog timer.)
Universal Peripheral Interface (UPI)
products that require interface personal computer other host buses, 8XC451, 87C453, 8XC576 ideal because they have built On-board means it's easier design serial controllers, servo controllers, keyboard scanners.
Smart Card
Philips Smart Card microcontroller provides features range applications devices, such credit cards, electronic keys, medical records, identification. Typical access control applications that Smart Cards satellite networks, mobile phones, computers, auto cards, electronic keys. Other Smart Card applications medical records, patient passports, cash cards. production markets, Smart Card used flow control, tool handling, maintenance, process control. Philips' Smart Card microcontroller, 83C852, features bytes ROM, bytes RAM, bytes EEPROM. 83C852 cryptographic calculation unit (CCU) enhance data security, comes credit card style package purchased form. Also available P83C855, P83C858 P83C864 designed specifically smart card applications.
Failure Detection Circuits
Other protection features integrated into Philips products with Watchdog timers Oscillator Failure Detection (OFD) Voltage Detection. Like Watchdog timer, these features generate reset oscillator frequency slows below predefined frequency range voltage levels part reduced. integrated protection features mean don't have spend extra design time adding components protect microcontroller system. result highly reliable design featuring reduced part count, quicker time-to-market, reduced cost.
Reduced
Recognizing challenges meeting certification, Philips developed family products that significantly reduced signatures. changing internal circuitry reduced microcontrollers, radiated noise reduced more than 20dB, especially important frequencies greater than 100MHz where board-level noise reduction difficult expensive achieve.
